Detailed Description

template<class Iterator>
class Fiber::ElementProxy< Iterator >

A proxy for Iterators, such that an Iterator's element looks like an Iterator's element (!), even though it isn't (the internal storage layout may be different).

Parameters

Iterator	The Iterator must export
array_t	(typedef) the type of each component
Components	(enum) the number of components
getComponent(int	idx,int c) a function returning a reference to the c'th component of the idx'th index in the field.

Constructor & Destructor Documentation

ElementProxy()

template<class Iterator >

Fiber::ElementProxy< Iterator >::ElementProxy ( const Iterator &  Owner, index_t  Idx  )

inline

Construct an ElementProxy as a reference to a specific element in a given array, which is accessed via the given Iterator.

Parameters

Owner

the Iterator referring to the array

Member Function Documentation

operator array_t()

template<class Iterator >

Fiber::ElementProxy< Iterator >::operator array_t ( ) const

inline

Implicit type conversion into an array element.

Note

This function creates a temporary object; it is convenient, but slow.
